A carbon steel ball with 25-mm diameter is pressed together with an aluminum ball with a 40-mm diameter by a force of 10 N. Determine the maximum pressure exerted by the steel ball on the aluminum ball. If the steel ball was pressed on an aluminum flat plate by a force of 10 N, what is the maximum pressure exerted by the steel ball? (νsteel = 0.292, νaluminum = 0.333, Esteel = 207 GPa, Ealuminum = 71.7 GPa)

answer 18.11 and 18.12
18.11 A steel ring with an outside diameter of 150 mm and an inside diameter of 100 mm is shrunk onto another steel ring with an inside diameter of 50 mm. An axial force of 56,54 kN is needed to push the rings apart. Calculate the pressure at the mating surface and the shrinkage allowance given that both rings are 20 mm thick and the coefficient of friction between the mating surfaces is 0,2. Using...
